Firefox Support Forum

We have a noticed a very strange behaviour with the latest FireFox (126). One of our webpage is behaving differently across our Integration and production environment. Both env are running identical code and similar network stack the only difference we have noticed so far is for our Integration env Firefox is sending the different user-agent string than for production.

Steps to reproduce: 1. Open https://integration4-view.publitas.com/automation-int4/reader-happy-path/page/1

2. Go to console and view navigator.userAgent the user-agent string will be:

    "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:126.0) Gecko/20100101 Firefox/126.0" 

3. Now open the same content on production -> https://view.publitas.com/automation-prod/reader-happy-path/page/1

4. Go to console and view navigator.userAgent the user-agent string will be:

   "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) FxQuantum/126.0 AppleWebKit/537.36 (KHTML, like Gecko) Chrome/103.0.5060.71 Safari/537.36" 

Our website changes behaviour based on which browser it is and based on second string our backend interprets the browser as chrome instead of Firefox.

If I change privacy.resistFingerprinting to True then the user-agent string is sent correctly.

Can you please help us identify what changed in the latest version that is causing this behaviour.

Version: 126 (64 bit) Test on Windows 11 and Mac OSX

Firefox 126.0 on a Windows 10 22H2

Hi I have been using Firefox maybe for 20 years... and I noticed in the last possibly 5 years has started to have problems after problems. More like bothers and I am not the only one!

Problems with YouTube videos either not loading properly or no audio and so on, tamed down at present! At some point I stopped using it years ago, then got back to it, but since I did a series of different things/work via browsers, I now have some others set to do one task/work.

Firefox is not only the ;standard browser for 'browsing' and basic shopping.

Anyway, this time from yesterday, DuckDuckGo Search not working any more.

There have not been any Windows or Security updates yesterday.

Any other search add-on works fine, but DuckDuckGo.

What I did:

1. Restarted browser - the obvious one 2. I do not really need to clear Cookies as I use an add on that does it for me as soon as I close a tab or browser 3. Downloaded 126.0 and re-installed it on top 4. No new add-ons were installed, but IU also re-started with all add-ons off 5. Cleared history - everything 6. Internet is fine, reset it - just in case, but also tested on other devices and DuckDuckGo works fine 7. My security is not blocking anything

Has Firefox 126.0 had an heart attack overnight, meaning there is a bug that comes out in certain conditions?

I just get from DuckDuckGo: There was an error displaying the search results. Please try again.

Any other Search work, even the less known such as Qwant and Mojeek. No idea. I wasted so much time... again.

Thank you M

PS I may have missed other things I did try and I may amend this post or add posts, if I cannot edit.

Hello,

We have a client using Azure Virtual Desktops. Most of the users prefer to use Firefox. We are having an issue that anytime we update Firefox and reimage the virtual hosts. When the users login they get a new Firefox profile. We have to remote in and copy their old profile data to the new profile.

Is there a better way for us to handle Firefox and profiling in and Azure Virtual Desktop deployment?

Tell me why google says this:

Unable to connect

An error occurred during a connection to www.googleadservices.com.

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.

when I click on an advert for a product provided (I assume) by google at the top of search results. I have cleared the cache and cookies. Latest firefox on ubuntu 22.

Hi, thank you for being there. I have a strange problem that started a while ago. Every time I restart the computer to refresh it, all my bookmarks and log-ins change. It seems as if they are set back to an old version, but I can't even remember ever having a setting like this. A lot of bookmarks folder are gone all together and others only have a few bookmarks left in them. I suddenly have to enter passwords to get into my email accounts. Even stranger, after a while it all goes back to my current setting without me changing anything. This can take days or weeks. All this makes me nervous about restarting my computer. Please understand that I am not a computer wiz, so if you send me complicated instructions on how to fix this, I probably won't understand them. I hope there is a simple explanation for this. Thanks, Monika

Running Firefox 126.0, which Firefox' About link says is current. Dell laptop running (current) Win10 Pro.

As recently as last Wednesday (15 May 24), everything was normal. Since yesterday (16 May), on the Wall Street Journal site, after I have logged in, I no longer have access to articles' comment threads. The Show Conversation button shows 0 comments (which is erroneous), and when I click the button, it changes to Hide Conversation (which is normal), but nothing else happens--just white space and no comments or comment text entry field.

On Fox News, the comment thread doesn't display, and there's not even displayed a link to a comment thread. Until yesterday, the thread normally displayed, but required login to comment. Since yesterday, logging in changes nothing: the comment thread still doesn't display at all.

On X (nee Twitter), when I click the login icon, I get the usual login box--but it's solid black with only a rotating arrow signifying "loading." It never finishes loading. An added fillip: X, as recently as last Wednesday, displayed in its usual black text on a white background. Now it displays as white text on a black background. I can click on X links sent to me and get that particular X post to display, but I cannot log in.

When I go to those sites in Edge, everything behaves normally: I have access to comment threads, and I can log in to X. One exception: X displays as white text on a black background on Edge, also. This doesn't seem to be an X thing, though; on my wife's laptop (Firefox 126.0), running WIn11Pro, her X display is the "normal" black text on white background.

I haven't changed any settings in Firefox. I do have a couple of ad blockers, and I've turned those off, one at a time and both together; that had no effect.

How can I get things back to normal in Firefox?

Thanks

In release 126.0 (64-bit) in Windows, persist logs in developer tools is not working for me. I've tried selecting and deselecting all the combinations in both settings areas in the split console, quitting the browser in between. Is there a new place to set this?

I've got my "homepage and new windows" setting set up with several "ext+container links so that my selected websites open in their respective containers : e.g. ext+container:name=Personal&url=https%3A%2F%2Fwww.facebook.com%2F%3Fsk%3Dh_nor

I open facebook in 2 seperate containers so that I can maintain 2 seperate personalities under facebook - e.g. I am a group admin within one, just a group member in another.

I have 2 urls defined in my "homepage and new windows" setting for these :

ext+container:name=Personal&url=https%3A%2F%2Fwww.facebook.com%2F%3Fsk%3Dh_nor ext+container:name=Facebook&url=https%3A%2F%2Fwww.facebook.com%2F%3Fsk%3Dh_nor

This was working fine without any issues. My sites opened up when I started my web browser and everything.

Recently, firefox has started up but my container tabs do not load automatically, I am getting a confirmation (I will post a screen capture as a comment).

Is there a way to turn this off and just open the tabs without a confirmation?

Hello, I have an odd situation. I have a new job, and want to sign into Firefox at work to sync my bookmarks and settings. The problem is that I seem to have saved the password wrong. My home laptop is working great as long as I don't sign out, but the system won't let me change my password without the old one. Is there any way to reset the password without having all my stuff wiped? Or can I do a backup on my home PC first, then do a reset/wipe, then restore? Thanks.

Had an update for Firefox happen last night and now the Duck Duck Go extension will not work. Just goes search not found?

Here is the error - There was an error displaying the search results. Please try again. When I turn off the extension Firefox runs fine.

I had turned off the extension first and turned back on same issue. Removed extension and reloaded same issue. Restarted router same issue. I have uninstalled Firefox and then reloaded same issue with Duck. Duck Duck Go works in my Edge browser

This is my Mac Monterey. My Windows 10 is in Safe Mode With Networking. The last update will not download. That version is 125.0.3. What's available under Windows updates does not download either. Now I am running my antivirus on my Windows to see if it runs clean. I do not know why I cannot apply these updates.

Suddenly, my login (user name & password) is not working on only one specific website, although it works perfectly with a couple other browsers. The site acts as though the information is not even being submitted-no change in site nor the "Login" button. I'm using the latest version of Firefox on Windows 10 and I have deleted all previous cookies and data, rebooted my PC with no difference in results. Thank you for any information.

Hi Support Team, Hope you are doing well. Do you have any issues with the service as I see from https://downdetector.pl/status/duckduckgo/ 144 was reported?

If you can just email me about reason if there was any malicious activities I happy to help.

Thanks RO

When we enter a search query on mobiles or on PC using Firefox we get:-

There was an error displaying the search results. Please try again.

This started happening today at about 10:45 (BST+2) Using Safari or the Galaxy search engine or using Chrome on the PC works fine.

At first we thought it might be a local problem so we re-booted our router - no result. We re-set Firefox on the PC - no result (anyway it is generalised).

Curiously WhatsApp is still connected (had to re-connect after re-set). So what is going on please?
